Inauguration du plus grand radiotélescope au monde en Chine

INTERNATIONAL 2

Le plus grand radiotélescope au monde a été inauguré dimanche dans une région montagneuse de la province chinoise du Guizhou (sud-ouest).

Peu après midi, dans une vallée karstique du district de Pingtang, des centaines d'astronomes professionnels et amateurs ont assisté au lancement officiel de la mission du Télescope sphérique de 500 m d'ouverture (FAST) qui scrutera l'espace et recherchera des signes de vie extraterrestre.

Les travaux de ce projets d'un coût de près de 1,2 milliard de yuans (180 millions de dollars) ont commencé en 2011, 17 ans après la proposition de ce télescope par des astronomes chinois.

L'installation de la structure principale du télescope, un réflecteur composé de 4.450 panneaux grand comme 300 terrains de football, a été achevée début juillet.

    Now that we've made it a solid week and a half into the new year, retailers are starting to look solidly toward spring for [url=http://www.topdesignerhandbags.co.uk]replica handbags[/url], even if I'm literally looking at snow on the ground outside my living room windows. I'll never turn down the chance to think of warmer weather or ogle some brand new bags, though, so let's do both. The best pre-orders I found were a mix of both Spring 2017 runway styles and impressive pieces from the non-runway portion of designers' collections. The widest selection was at Neiman Marcus, but other sites are catching up as we get closer to spring for [url=http://www.nicerolexsale.co.uk]rolex replica[/url] sale. Wow, now you see these premium brands start using embroidered and pearl rivets, which had been beautifully used in Coach 2016 Fall 1941 western collection. Not to mention this Moschino Floral Applique bag, and the Fendi Allover Flowers Peekaboo Bag (listed in another thread) are copying the concept of [url=http://www.celinebags.co.uk]celine outlet[/url] bag but in an ugly way. That leather on the Sophie Hulme bag in slide 22 looks so cheap! I would never be able to pay $975 for a satchel that looks like it's from Forever 21. But I know those Coach haters will keep saying Coach copies from other brands. and keep paying triple price for these top brand names. no matter how ugly the bag itself is. Coach did not invent the idea of decorating [url=http://www.cheapchanelonline.co.uk]chanel replica[/url] bags with pearls & embroidery lol. Coach does indeed copy from other brands. Most brands gain inspiration from the hottest styles, its just the way things work.
